Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The NM_000179.3(MSH6):c.203A>T(p.Lys68Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000741 in 1,349,356 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. K68Q) has been classified as Uncertain significance.

Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jan 02, 2023 | The p.K68M variant (also known as c.203A>T), located in coding exon 1 of the MSH6 gene, results from an A to T substitution at nucleotide position 203. The lysine at codon 68 is replaced by methionine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
